The water molecule, Fig. 17-42, has a dipole moment p which can be considered as the vector sum of the two dipole moments, P¡ and pP2, as shown. The distance between each H and the O is about 0.96 x 10-10 m. The lines joining the center of the O atom with each H atom make an angle of 104°, as shown, and the net dipole moment has been mea- sured to be p = 6.1 × 10-30 C · m.

Some types of molecules that do not possess an intrinsic electric dipole moment can be given one by an external electric field in a process called charge separation, or polarization. In this process, their internal charge distribution becomes distorted by the field, which results in the region of a molecule on the side in the direction of the field gaining a positive net charge and the region on the other side gaining a negative net charge. Both charges have equal magnitudes, and the electric neutrality of the molecule as a whole is maintained. The electric field is said to induce an electric dipole moment in such a molecule. When the field is canceled, the molecule reverts to its unpolarized state and loses its electric dipole moment. The electric behavior of such a molecule can be modeled by a pair of ±1.60×10^−19 C charges connected by a spring with force constant 0.000711 N/m. The spring must be imagined as possessing zero relaxed length so that normally the charges overlap and the…
